Channel Master's 3414 is a compact, versatile RF distribution amplifier designed for indoor use with coaxial cables. It lets you distribute amplified antenna or cable TV signals to as many as four TVs without the signal degradation caused by splitters.
The 3414 can improve reception whether the problem is weak signal strength at your antenna, or loss of signal quality due to a long cable run. Unlike the inexpensive boosters you find in hardware stores, the 3414 is a "bi-directional" design that provides a return signal path for use with a cable box or cable modem (return signal is not amplified). The included AC power supply connects to the 3414 via a short length of coax cable, which is also included.
